Cleaning Modes and Pattern  
Virtual Wall® Optional accessory for all models.  
Virtual Walls create an invisible barrier that your Roomba won’t cross. That makes it easy  
to confine it to a particular room or area, and prevent it from getting too close to anything  
delicate or dangerous.  
Roomba uses iAdaptResponsive Cleaning Technology, an advanced, proprietary  
system of software and sensors. iAdapt allows Roomba to actively monitor the cleaning  
environment more than 60 times per second and respond with over 40 different mobility  
behaviors to clean the room more thoroughly.  
• Each Virtual Wall needs two C alkaline  
Roomba 700 Series has 3 cleaning modes you can select:  
batteries (not included).  
Clean Mode – Roomba automatically calculates the room size and adjusts its cleaning  
time appropriately.  
You can set the Virtual Walls to block an  
opening of up to 7 feet (2 meters).  
It creates a cone shape barrier, so the  
beam gradually gets wider.  
Spot Mode – Roomba will spiral approximately 3 feet (1 meter) in diameter  
and then spiral back to where it started – an intense, localized clean for those  
quick fixes.  
• For best results, place the Virtual Wall  
on the outside of the doorway you  
want to block. Point the arrows on the  
top towards the opening.  
Scheduled Cleaning Mode – Roomba leaves its Home Base, cleans, and then  
returns to recharge when its done.  
Manual Virtual Wall  
Surfaces  
Turn on a Manual Virtual Wall by hand at the beginning of the cleaning cycle.  
It will shut off after 135 minutes. If the power light blinks green, it means you’ll  
need new batteries soon.  
Your Roomba works on pretty much anything – wood, carpet, tile, vinyl and linoleum,  
adjusting to different floor types. It automatically senses stairs and other drops.  
It might stall when confronting round edges and might slide over particularly slippery  
surfaces. Very dark floors may impede its sensors. Roomba is not designed for  
use outdoors.  
Auto Virtual Wall  
• When an Auto Virtual Wall is set to “AUTO” mode, the power light continuously blinks  
to indicate it is on. When battery levels are low, the Virtual Wall continuously blinks  
twice to indicate that it needs new batteries. When in AUTO mode, the batteries  
should last for around six months. To save on batteries, just switch it to OFF.  
Anti-tangle system  
Roomba won’t get caught up in tassels or fringes. If it senses a tangle, it  
automatically stops its brushes and spins them in reverse to free itself.  
Virtual Wall Lighthouse™ Accessory for models 780 and above only.  
Home Base  
Position the Home Base on a hard, level surface against a wall. Make sure its at least  
4 feet (1.5 meters) from any stairs and that your Roomba has a clear path to reach it.  
A Virtual Wall Lighthouse can act as both a Virtual Wall and a Lighthouse.  
In Lighthouse mode, it helps your Roomba navigate around your home.  
In Virtual Wall mode, it blocks off areas you don’t want cleaned.  
When Roomba has finished cleaning, it will return to its Home Base to charge.  
The light on the Home Base stops blinking and turns solid green when Roomba  
makes a good connection. Then, Roombas battery indicator will pulse amber to  
show it is charging, and will turn solid green when Roomba is fully charged and  
ready to clean again!  
Simply use the Mode Selector to make your choice. Either way, it turns on and off  
automatically as you turn your Roomba on and off. When on, the light on top is lit.  
Each Virtual Wall Lighthouse needs two C alkaline batteries (not included). A flashing  
power light means the batteries need replacing soon.

Battery storage and charging  
Your Roomba is powered by a rechargeable battery. Before using your Roomba  
for the first time, you’ll need to charge the battery overnight.  
• Make sure your Roomba is fully charged before each cleaning cycle.  
For maximum battery life, always store your Roomba plugged in.  
• When your Roomba is on the Home Base, make sure the Home Base  
power light is on.  
• If you return your Roomba to the Home Base / battery charger after leaving  
it off for a long time, it will start a special Refresh Charge mode and the battery  
indicator will pulse quickly. If possible, don’t interrupt the Refresh Charge mode.  
• For long-term storage, fully charge the battery, remove, and store it in a  
cool, dry place.  
How to use the Lighthouse mode  
Simply place a Lighthouse in the doorway  
with the logo facing forward. When it has  
completed the first room the Lighthouse  
will help Roomba navigate around your  
home allowing it to clean room-to-room.  
When Roomba has completed cleaning,  
the Lighthouse will direct Roomba back  
to its Home Base for recharging.  
How to remove your battery  
If you won’t be using your Roomba for an extended period, we recommend that you  
remove the battery. To access the battery, turn Roomba over and remove the two  
screws that hold Roombas battery cover in place.  
You can use Lighthouses and Virtual Walls  
at the same time, but avoid placing them  
too close to each other, to the Home Base, or to furniture that could block the invisible  
beams. Otherwise your Roomba might not recognize the Lighthouses or be able to  
return to Home Base.

What does it mean?  
The Anti-tangle Indicator turns on while Roomba is freeing  
itself from a tangle.  
The Dirt Detect Indicator flashes when dirt is detected and  
persistent pass cleaning pattern is initiated.  
How to use the Virtual Wall mode  
In Virtual Wall mode, the Lighthouse creates an invisible barrier that your Roomba won’t  
cross. It automatically turns off when your Roomba is turned off.  
The Troubleshooting Light blinks when there is an issue  
(see pages 11 and 12).  
Simply place the Virtual Wall Lighthouse in the center of the doorframe. Unlike a Virtual  
Wall, a Virtual Wall Lighthouse features a range selector that you can use to adjust the  
length of the barrier – up to 8 feet (2 meters) – (a longer range will drain the  
battery faster).  
The Full Bin Indicator (models 770 and above) lets you know  
when the dust bin is full and needs to be emptied.  
The Battery Indicator shows the battery status.  
Solid red --- Battery drained  
Amber pulse --- Charging  
Solid green --- Fully charged

Roomba battery pack and charging  
Frequently asked questions  
• Charge using a standard outlet only. Product may not be used with any type of power  
converter. Use of other power converters will immediately void the warranty.  
• Use only the battery charger supplied by the manufacturer to charge this device.  
• Do not use a battery charger with a damaged cord or plug.  
• Charge indoors only.  
• Roombas battery charger may be protected with a surge protector in the event of severe  
electrical storms.  
• Never handle the battery charger with wet hands.  
Why does my Roomba’s side brush occasionally spin backwards?  
When caught on items such as carpet tassels or wires, the side brush may spin slowly or even  
backwards to free itself. This may also occur on thick carpets. If it does this at other times, you  
should clean the brush.  
Why does my Roomba occasionally make a thumping sound?  
When Roombas brushes encounter items such as carpet tassels or wires, the brushes will  
briefly reverse direction to get free. This makes a thumping sound. If you hear a thumping  
sound at any other time, you should clean the main brushes.  
• Always disconnect Roomba from the battery charger before cleaning.  
• Please ensure voltage rating for enclosed battery charger matches standard outlet voltage.  
Why doesn’t my Roomba slow down as it approaches certain obstacles?  
Your Roomba usually identifies obstacles quickly, allowing it to slow down and gently touch the  
obstacle with its bumper before changing direction. However, it may be less effective at sensing  
extremely dark surfaces, or objects under 2 inches (5 centimeters) wide.  
What if I need further help or accessories?
